'quickly-altered' originates from the combination of 'quickly' and 'altered', where 'quickly' is derived from Old English 'cwiclice', meaning 'lively' or 'rapidly', and 'altered' comes from Latin 'alterare', meaning 'to change'.

'quickly' evolved from Old English 'cwiclice', and 'altered' from Latin 'alterare', eventually forming the modern English compound adjective 'quickly-altered'.

Initially, 'quickly' meant 'lively' or 'rapidly', and 'altered' meant 'to change'. Together, they convey the idea of something being changed rapidly.
